2013-01-14zebra: don't overrun afi/safi array boundariesLeonid Rosenboim
zebra was not checking afi/safi values. This was leading to crashes where these values were coming directly from some protocol's on-wire fields. Safeguarding them in zebra is a good start. Signed-off-by: David Lamparter <equinox@opensourcerouting.org>
2012-11-30zebra: add module to communicate routes to FPMAvneesh Sachdev
Enhance zebra to send routes to the (optional) Forwarding Path Manager component using the interface defined by fpm/fpm.h. * configure.ac - Add --enable-fpm flag. The FPM-related code in zebra is activated only if the build is configured with '--enable-fpm'. - Add HAVE_NETLINK automake conditional. This allows us to conditionally build netlink-dependent C code. * zebra/{rib.h,zebra_rib.c} - Add the 'fpm_q_entries' field to the rib_dest_t structure. This allows dests to be placed on the fpm queue. - Define a couple new rib_dest_t flags that hold FPM-related state. - Invoke the zfpm_trigger_update() function for a route_node whenever the information to be sent to the FPM changes. - rib_can_delete_dest(): Return FALSE if we have to update the FPM about the given dest. This ensures that the dest is not deleted even if there are no ribs hanging off of it. * zebra/zebra_fpm.c This file holds most of the code for interacting with the FPM. - If quagga was configured with '--enable-fpm', periodically try to connect to the FPM. - When the connection comes up, enqueue all relevent dests to the FPM queue. - When the FPM socket is readable, dequeue the next rib_dest_t from the FPM queue, encode it in to a message and send the message to the FPM. - When the connection to the FPM goes down, remove all dests from the FPM queue, and then start trying to connect to the FPM again. - Expose the following new operational commands: show zebra fpm stats clear zebra fpm stats * zebra/zebra_fpm_netlink.c - zfpm_netlink_encode_route(): Function to encode information about a rib_dest_t in netlink format. * zebra/zebra_fpm_private.h Private header file for the zebra FPM module. * zebra/zebra_fpm.h Header file exported by zebra FPM module to the rest of zebra. * zebra/debug.c Add the 'debug zebra fpm' command. * zebra/main.c Initialize the zebra-FPM code on startup. * zebra/misc_null.c Add stub for zfpm_trigger_update(). * zebra/Makefile.am - Include new file zebra_fpm.c in build. - Include zebra_fpm_netlink.c in build if HAVE_NETLINK is defined. * vtysh/Makefile.am Include zebra_fpm.c in list of files that define cli commands.

2012-11-30zebra: extern/extract some functions from rt_netlink.cAvneesh Sachdev
* zebra/{rib.h,zebra_rib.c} Add nexthop_type_to_str(), which returns a human-readable string corresponding to a nexthop type. * zebra/rt_netlink.[hc] - Add new header file that exposes some existing and new netlink-related functions from rt_netlink.c to the rest of zebra. addattr32 addattr_l rta_addattr_l nl_msg_type_to_str (new) nl_rtproto_to_str (new) - Use nexthop_type_to_str() instead of the static array 'nexthop_types_desc'.

2012-11-30zebra: add iterator for walking all tables in RIBAvneesh Sachdev
* lib/zebra.h Add macro ZEBRA_NUM_OF, which returns the number of elements in a static array. * zebra/rib.h Add the rib_tables_iter_t structure and associated functions, which allow one to walk all tables in the rib. * zebra/zebra_rib.c - Add vrf_id_get_next() to retrieve the first VRF id (if any) that is greater than a given VRF id. - Add rib_tables_iter_next().

2012-11-30zebra: add way to determine VRF/AFI/SAFI of tableAvneesh Sachdev
Add some code that allows us to determine which VRF and AFI/SAFI a given RIB table corresponds to. * zebra/rib.h Add rib_table_info_t structure, which contains information about the VRF, AFI and SAFI that a table is for. * zebra/zebra_rib.c - Add the vrf_table_create() function, which creates a table and sets its 'info' pointer to a newly created rib_table_info_t. The 'info' pointer allows us to go from a route_node or a table to the associated vrf. - vrf_alloc(): Use vrf_create_table() to create tables. * lib/memtypes.c Add memory type for rib_table_info_t.

2012-11-30zebra: add structure to hold per-prefix state in RIBAvneesh Sachdev
Add the rib_dest_t structure to hold per-prefix state in the routing information base. This gives us an appropriate place to maintain the queueing state of a route_node. Queuing state was previously being stored on the first rib in the list of ribs hanging off the route_node. * zebra/rib.h - Add new structure rib_dest_t. - Remove the rn_status field from 'struct rib', it is no longer required. - Add macros (RNODE_FOREACH_RIB, RNODE_FOREACH_RIB_SAFE) for walking all 'struct ribs' corresponding to a route_node. These hide the fact that there is an intermediate rib_dest_t structure. - Add a few utility inlines to go between a rib_dest_t and associated structures. * zebra/zebra_rib.c - rib_link()/rib_unlink() Tweak for new behavior, where the 'info' pointer of a route_node points to a rib_dest_t. The list of ribs for a prefix now hangs off of the dest. Change the way we ref count route_nodes. We now hold a single ref count on a route_node if there is a corresponding rib_dest_t. - Maintain the queuing state of a route_node on the flags field of the rib_dest_t. - Add the rib_gc_dest() function, which deletes a rib_dest_t if it is no longer required. A rib_dest_t can be deleted iff there are no struct ribs hanging off of it. - Call rib_gc_dest() any time we unlink a rib from the rib_dest_t. Currently we only need to call it once, just before we return from rib_process(). * zebra/{redistribute,zebra_rib,zebra_snmp,zebra_vty}.c Use new macros to walk over route_node ribs. * lib/memtypes.c Add memory type for rib_dest_t.

2012-01-02zebra: fix ifindex test condition (BZ#487)Matthias Ferdinand
When the same ip address is used on several interfaces, and one of them gets deleted (or equivalent: set to down and then address removed), rib_delete_ipv[46] will also remove the connected route from other interfaces. rib_delete_ipv[46] is called twice when an interface is deleted: - for the "ifdown" event - for the address removal (note: this may be specific to the netlink interface of linux) The second call does not find the connected route to that same ifindex anymore, but deletes similar connected routes to any other ifindex instead. Reason: the ifindex check is on the same level as the check for ZEBRA_ROUTE_CONNECT/NEXTHOP_TYPE_IFINDEX. If everything matches except for the ifindex, the "else" part (intended for different route types) is executed, thus removing the route from the wrong interface. fix: move ifindex check inside the "then" part of the check for ZEBRA_ROUTE_CONNECT/NEXTHOP_TYPE_IFINDEX. Now connected routes to other ifindexes will not spill over to the "else" part for different route types anymore.
2012-01-02zebra: ZEBRA_HELLO and mopping up routes (BZ#448)Vyacheslav Trushkin
ZEBRA_HELLO message is used by routing daemons to inform zebra what type of routes daemon will be announcing to zebra. Also zebra uses route_type_oaths array to track which daemon announces which protocol. Zebra mops up routes if daemon didn't for some reason.

(rib_queue_qnode_del) Removed, deleted RIBs no longer deleted via the queue. (rib_queue_add_qnode) deleted (rib_queue_add) Only the route_node is queued for best-path selection, we can check whether it is already queued or not and avoid queueing same node twice - struct rib * argument is not needed. (rib_link/unlink) (un)link RIB from route_node. (rib_{add,del}node) Front-end to updates of a RIB. (rib_process) Reap any deleted RIBs via rib_unlink. Unset the route_node 'QUEUED' flag.
